Its fit-out division is working on two office revamps for IBM UK in Edinburgh as well as the new site for business analytics software firm SAS at the Cuprum building in Glasgow.
Having recently completed a refurbishment of Kirkgate House in Aberdeen for Land Securities, the Clark Contracts team was asked to take on a fit-out there by civil engineer Atkins.
The company's west coast division is building workshop units in Irvine as well as upgrading the Tay House office block in central Glasgow.
On the east coast, Clark Contracts is working for St Andrews University to create new research laboratories, workshops and storage areas for the school of geography and geosciences.
Meanwhile the small works division is involved in projects for two Edinburgh University buildings and the Dumfries & Galloway College centre for renewable energy and sustainable technology. It is also involved in refurbishments for Rank casinos in Glasgow and contracts with Police Scotland in Ayrshire.
Steve Clark, executive chairman of Clark Contracts, said: "It's always great to get the New Year off to a flying start and we are very determined to maintain the momentum throughout 2014.
"It is especially pleasing that the new work has been secured across the whole country, with both our construction divisions, covering the west and east of Scotland, attracting work on significant new, high-profile projects.
"We have also now secured three major contracts in Aberdeen and believe there is lots more potential to win more work there this year."
